Abstract

A method for achieving the soft or softer handoff process such that the performance of a system is improved is based on delaying the softer handoff process. <??>Reverse link demodulation in each sector may continue with or without the transmission of the forward link. The operation could be based on the signal strength of the reverse link signal or the forward link. It is also possible to combine two or more methods to create a hybrid symbol. <IMAGE>
